Some manual or another for TR3's (might be the factory manual, but I don't 
have one handy)actually recommends lapping down the pump body to reduce the 
end clearance for the rotors.  Obviously, if you then fit new rotors, they 
will have to be shortened to match ...

The moral is, always check the clearances during a rebuild.
